Toall whom'itjmay concern:

Be it'k-nown that I, EDWIN HENDRY BEN- nnns a citizen of the UnitedStates, residin 'in. Elizabeth, in the county of Union an State of'NewJerse have invented a certain new and useful Si e Frame for Car-Trucks,of which the following is a specification.

Tlhis invention is a side frame for car trucks, and. appertains moreparticularly to trticksforfreight cars.

fifireat difliculty has been experienced in.

practimi in Producing a side frame for trucks which is simple andeconomical in construction, and yet possess 'the' desired strength anddurability. f a 1 "In thep'resent invention Ihave accomlished these andother objects, and have designed a frame of the characterunder'consideration poss'essinga maximum amount of strength with ",aminimum amount of material. #Tbese results have been achieved byconstructing certain membersof the theme from" material havin specialforms,

m crosssqction, and by so tributin'g the material as to produce thegreatest stren th at the particular points in theframe which experiencehasproved are most apt to yield and break when 'subjectedto the heavyloads.

- and strains incident to their 115 6.

The new sidei'ra'me is simple and economical to construct, can bequicklymounted for use and, in practice, has proven to posses's greateficiency and durability.

In the accompanying drawings, I have illustrated one ractical embodimentof the nrfis' to ,be understood as illustrative only,- andnot-asdefining' the limits of the inven- L;Figure l is a plan View ofthe framej and Figs.'2 and 3 are side and end views thereof,

a sectional view, showin apart of the ame ,work in elevation, on me"7:7of Fig. 2..

Fig. 8 is a sectional viewon line 8+8 of Fig. .2; and Fig. 9 is asectional view on line 99 ofFi'g.2,.

These arts form a frame, substantially triangu'a'r in shape, andextending across which are the uprights, d, d, for the purpose ofstrengthening it.

The member, afin cross section, for the main portion of its length is ofthe form .shown in Fig. 5, the same consisting of the upper web,-e,-h'aving the depending flanges f, f, from which extend the reenteringa g i .I l ,0 members, I), b', are substantially rectangular in crosssection, as shown in Fig. 9, and are provided at their upper sides withribs, 72., 7t ,'s ee Fig. 9. 1 a I The base member, .0, which isskeletonized, is composed of. a bottom plate, '01, side plates,

These hangers are cast integral with the u rights, and, by virtueof the additional meta enter frame at polnts normally subjected to-greate5 ing into their construction, strengthen the strains, and inwhichrespect prior frames were defective. I

The top member, a,= the members, I), b, the base 'member,'c, the uprihts, 11,11, and thehangers, 1', are preferab y'castin one piece.

The top edge of the base member, a, is recessed at 'ltfltt', see-Fig. 2,for the punpo se of. receiving the angle shaped plates, 1;, 'v whichserve to connect. the two side frames of'the truck, tying them tpgetherand tending to" I thetruck square, the said an 1e plates ,heid in placeby bolts, w, w ,and w, 11"

The device as described, possesses pronounced strength and rigidity,being particularly strong at those points which experience-has shown tobe the most susceptib breakage, and et the frame isso shaped, and
